Sonoma Coast


The Russian River Valley climate is defined by its proximity to the ocean and is bordered by the Russian River and the Mayacamas mountains. Coastal breezes bring cooling fog through the Petaluma wind gap in the morning and evening, balancing the afternoon heat enjoyed in this appellation. This temperature differential creates excellent conditions for our Chardonnays as the fruit is afforded a long growing season, allowing time for optimum fruit maturity.

The Purrington Rued Vineyard, Ritchie Vineyard, and Dutton Ranch Sebastopol Vineyards are the fruit sources for our vineyard designated Chardonnays and our True Course, The Voyage, and Absolutely Eloise Chardonnays. The fruit from each of these vineyards comes from very old vines which lends the complexity and intense fruit flavors which are key to the composition of these memorable Chardonnay wines.

Recent Parker Wine Advocate honors:

Chateau Boswell True Course Chardonnay 2015; "The 2015 Chardonnay True Course gives up a very youthful nose of fresh grapefruit, white peaches, orange blossoms and marzipan with wafts of yuzu zest and crushed stones. Medium to full-bodied with a wicked backbone of invigorating freshness, the palate packs in the citrus and mineral layers with a satiny texture and fantastic length." 97 points


The beautifully managed Sun Chase vineyard offers everything Pinot Noir needs to achieve perfection. High above the fog line at a 1400 foot elevation on Sonoma Mountain at the confluence of the Petaluma Gap is the location of the Chateau Boswell block. Early morning sun provides a full day of sun exposure while the cool ocean breezes protect the fruit from too much heat. This allows for a long growing season providing us with fully ripe rich fruit for maximum flavor components.
